Page 16: Product Description
Product description 3 Product description 3.1 Function The HeptaDry screw pumps function according to the double screw-pump principle. Two screw rotors rotate in the compression chamber. The medium to be pumped is trapped between the individual screw coils, compacted and transported to the gas outlet. During the compaction process, the two screw rotors do not come into contact with each other, nor with the suction chamber. -
